水草情迷

實情大家係setup缸時有冇考慮過會否超重呢?
有冇人知香港住宅樓宇每sq. meter 可承受幾多kg呢?

你個缸唔係好大咋？！未免太居安思危！

我諗你個缸大唔得過個浴缸卦.......

實情係咁既..........
我打算setup 一個約兩呎既魚缸架,
放兩至三個約兩呎缸,照 60cmx40cmx45cm Ht.計既話,
每個會有108Kg 水, 3個即324kg,
加埋缸本身, 砂石,魚缸架及器材等.......可能會有成500至600kg....
如果重量"最"晒落魚缸架既4隻腳度........我惊力度太集中, 造成危險
(同浴缸唔同, 浴缸打橫攤響度, 受力面積大好多, 又唔係成日裝滿水)
以前做珠寶行裝修工程時記得放夾萬時搵consultant 計過數, 印象中商業樓既負重每平方米都唔係好高(好似只係1吨度), 要加鐵板係底攤分重量........
因此有這樣既問題

咦?一個架放三個缸,咁上面果個咪好高,會唔會好唔方便呢?

please reply this post if someone know about it

because i am going to setup a 架 for 2個 48"x27"x22"缸 plus other small tanks

total weight will be around 1200KG

thanks

每座大廈都唔同,如果真係要Check就要睇圖積先知...

又講吓D無無聊的經歷 有次上門做工，見客有一個約4 呎幾高乘6 呎的魚缸，好奇問做左幾錢。嗰客話免費的。是朋友住公屋養魚的，點知有日房署有人上門，話怕樓宇承受不起，要馬上遷走。嗰客住村屋底層，甘就多謝曬啦。又免費送貨，又免費魚缸加器材

我有個朋友好似係做積師, 這是他給我的香港建築法例指引 :

http://www.justice.gov.hk/blis.nsf/e1bf ... enDocument

"其中一般住宅平面負荷為 2.5kPa. 這是法例規定的最小負重.
任何住宅都一樣. kPa = Kilo Pascal." 即係.. haha..網上算式有好多, 不過都係無信心計得岩... 個朋友好似溫緊書考牌, 都係費事煩佢了

1 kPa is approximately equal to 100 kg /square meter
2.5 kPa ~ 250kg/square meter
If your tanks add up to 500 ~ 600 kg, metal bar/metal plate is needed to spread the weight to the floor.
If you have the structural plan of your building, you may put your tank over the beams as the loading can be much higher.
1200kg is a bit dangerous for a normal domestic building.

oh shit???????????

i am planning to make a 4ft shelf and take a few tanks
total weight about 1200KG................

Fox, its a but dangerous or "VERY" dangerous???

coz the plan is on the move...

cant change anymore...............

vc

found it la

30cm x 30cm should at least support 3kN(300KG)????????

thanks for the link from 玻璃

please final check am i correct or not

vc

30cm x 30 cm with 3kN is for concentrated load.
vchie,
in your case, it depends on the area of your tank and the position in your house placing the tank. If your place it over the beam (can afford uniform load of 15 kN), it may be OK.
But I'm not working in this field, you better consult some professional.

250kg per square meter.......終於知道了, thx. fox.
but, I think many many people have the tanks exceed this weight.

Also, watch out that whether the load is spread out over large area or concentrated in a small area. If all weight is concentrated on a small footprint, it is very dangerous.
The link from 玻璃 said concentrated load is spread over an area of 30cmx30cm (1 sq feet). So the final force on the floor depends on the contact area between the legs of your stand and the floor. Better consult someone with expertise on building/structure. Poking a hole on the floor is not fun!
